I was invited to take a ‘Green Hue’ sightseeing trip. Standing on Gia Vien bridge and look northwards on a sunny day, I saw River Huong was supported with different colors: yellow of the Golden Shower tree, scarlet of the Flamboyant, velvet of the crape-myrtle, blue of the sky and green of water. It made me think of a picture of happiness and well-being in the deep memory of more than thirty years: Sinh paintings.
